Non-Destructive Testing

Non-destructive testing, or NDT, refers to a set of inspection methods use to analyze and evaluate the soundness of a material, without causing any damage to the item being inspected.

Elite Metal Finishing has an on-site laboratory to conduct non-destructive testing. Our NDT operators are certified in Magnetic Particle Inspection and Liquid Penetrant Inspection testing, all of which are conducted in-house.

Magnetic Particle Inspection is used for locating stringers, indications, inclusions and discontinuities on the surface and subsurface in ferromagnetic objects. The test can be used on a wide variety of materials, as well as various shapes and sizes. It is also an extremely economical type of testing that provides almost instantaneous results.

Pre-Penetrant Etching is a very light etching process used to remove traces of smeared metal introduced during previous processes, or light oxide layers that may have been formed. The Pre-Penetrant Etch assists in revealing discrepant conditions that would otherwise have been masked. Performance of pre-penetrant etching is driven by specification and/or customer requirements.

Magnetic Particle Inspection procedures are in compliance with: ASTM E 1444, AC7114-2, BPS 4075, DPS 4.704, PS 21201, BAC 5424.

Fluorescent Liquid Penetrant Inspection is appropriate for finding discontinuities that are open to the surface, such as seams, porosity, shrinkage, weldment flaws, cracks and more. It is a popular method of testing, due in part, to its low cost. It too can be used on wide array of materials, as well as different sizes and shapes. The fluorescent dyes used are capable of entering minute defects that would not normally be detectable by the human eye.

Fluorescent Liquid Penetrant Inspection procedures are in compliance with; ASTM E 1417, AC7114-1, BPS 4089, DPS 4.707, PRC-6506, PS 21202, STP53-201, ACS-PRS-7005, BAC 5423.
